造型材料在铸造生产中的重要性造型和制芯是铸造生产中费用最高的工序。据最近西德有关统计资料报导,造型和制芯这一工序占铸件生产成本一半左右,金属熔炼及其后处理占四分之一,还有四分之一花费在清砂和其后修整等工序上,而出砂清铲工作成本又有75%与造型材料有着密切关系。因此,铸件生产的总成本中,60~
The Importance of Molding Materials in Casting Production Molding and core making are the most expensive processes in casting production. According to recent statistics on West Germany, molding and core making process account for about half of the cost of casting, metal smelting and post-processing accounts for a quarter, and a quarter for sand cleaning and subsequent trimming Process, and sand shovel work cost 75% and molding materials are closely related. Therefore, the total cost of casting production, 60 ~
